Application July 16, 1958, Serial No. 748,882 1 Claim. or. 98-83) This invention relates to improvements in covers for chimneys of dwellings, especially.

The primary object of the invention is to provide a cover for such chimneys adapted for installing thereon in elevated position to shield the chimney against rain or the like entering the same and reduce heat loss from fireplaces and the like while not interfering with chimney updraft, and which may be lowered'into chimney capping position if it is desired to close a chimney entirely and will be anchored in place against being blown off a chimney in either position and Without separate fasteners requiring attachment to the chimney, but by suspended weight means.

Another object is to provide a cover for the above purposes which may be manufactured from different kinds of sheet and strap metal parts so that it is well adapted for inexpensive production. 1

These together with other objects and advantages which will become subsequently apparent reside in the details of construction and operation as more fully hereinafter described and claimed, reference being had to the accompanying drawings forming a part hereof, wherein like numerals refer to like parts throughout, and in which:

Figure 1 is a fragmentary view in perspective illustrating the improved chimney cover installed on a single flue chimney and in elevated position;

Figure 2 is an enlarged view in vertical section taken on the line 2-2 of Figure 1;

Figure 3 is a bottom plan view of the cover detached;

Figure 4 is a fragmentary view in side elevation, partly in section, of a modified embodiment of the chimney cover for a plural flue chimney;

Figure 5 is a view in vertical section taken on the line 55 of Figure 4;

Figure 6 is a fragmentary view in vertical section illustrating the chimney cover of the preferred embodiment lowered into chimney capping and closing position, and

Figure 7 is a fragmentary view in vertical section of another modified embodiment of the chimney cover.

Referring to the drawings by numerals, the preferred embodiment of the chimney cover of this invention, as shown in Figures 1 to 3 and 6 comprises a hood 1 of rectangular shape, generally, and of sheet metal preferably, and which is of a size to overlap the flue liner 3 of a single flue chimney 5 to cover the flue.

The hood 1 comprises a peaked top 7 forming downwardly slanting top sections 9 for water draining purposes and is provided with a depending marginal flange 11 for seating on top of the chimney in surrounding relation to the flue liner 3 so that the hood may be lowered onto the top of the chimney 5 to cap and close said chimney with the top 7 of the hood I raised above the chimney 5 for a purpose presently seen.

Supporting legs 13 of strap metal are provided on the hood 1 in a 90 angular relation for seating on top of the chimney 5 to support the hood 1 in elevated position over the liner 3 and said legs are detachably attached to the top 2,918,859 Patented Dec. 29, 1959 "ice sections 9 in inwardly spaced relation to the flange 11 by inwardly bent upper, apertured ends 15 on said legs and bolts 17 passing through said ends 15 and said top sections 9.

A hold-down weight 19 suspended from the hood 1 and in the flue liner 3, by means presently described holds the legs 13 seated on top of the chimney 5 to stabilize the cover, and the weight 19 is sufliciently heavy to hold the hood 1 and legs 13 down in a strong wind and updraft through the chimney.

' The weight 19 is preferably tubular and of less width than the flue liner 3 so that it will not impede updraft in the chimney 5 and is suspended by means of resilient, bendable strap metal hanger bars 21 converging downwardly from the bolts 17 in angular relation in the top of the flue liner 3 to suspend the weight 19 in said flue liner 3 below the top of the chimney 5 in centered position in the flue liner 3 and in spaced relation thereto. The hanger bars 21 are detachably bolted, as at 23, at lower ends 25 thereof to the upper end 27 of the weight 19 and are provided with upper *inturned, apertured ends 29 detachably clamped to the ends 15 of the legs 13 by the bolts 17.

In the modified embodiment of the chimney cover for a plural flue chimney, an oblong rectangular hood 31 is provided for covering at its ends a pair of twin flue liners 33 of a chimney 35 and is constructed similarly to the hood 1 with a top 37 having downwardly slanting top sec tions 39 for water draining purposes, and a depending marginal flange 40 for the same purpose as the flange 11. Adjacent its ends, the hood 31 is provided with pairs of opposite supporting strap metal legs ,41 for resting on top of the chimney 33 to support the hood 31 in elevated position and said legs are detachably attached to the hood 31 at opposite sides of said hood by inwardly bent upper ends 43 and bolts 45 all as in the preferred embodiment.

A pair of weights 47, like the weight 19 are suspended in the pair of lines 33 by pairs of downwardly converging, resilient and bendable strap metal hanger bars 49 detachably attached to the weights 47 and to the hood 31 by the bolts 44 and 45 respectively, as in the preferred embodiment.

In the modified embodiment shown in Figure 7, extensible legs, as at 51, for supporting the hoods, for instance hood 1, may be provided for varying the height of the hood 1 above the chimney 5 and may comprise upper and lower strap bar sections 53, 55, respectively slidably connected together by slot and bolt connections 57, 59 for extension of said legs with the upper sections 53 detachably attached to the hood 1 as in the other embodiments.

The manner in which the described chimney closures are applied, or installed on the hoods 1, 31 in raised position will be readily understood from the foregoing.

For lowering the hoods 1, 31 into position to cap and close the chimneys 5, 35, the legs 31, 41 and the hanger bars 21, 49 on the respective hoods 1, 31 are detached for removing the legs and the hanger bars 21, 49 are then attached to the hood 1, 31, respectively, by the bolts 23, 45. The hoods 1, 31 are then pressed down to rest on top of the chimney 5, 35 respectively and to bend the hanger bars 21, 49 over the rim of the flue liners, for instance liner 3, as shown for instance at 61 in connection with the hanger bars 21, and whereby to wedge the hangerthe chimney 5 in both the raised and lower positions of said hood 1.

The foregoing is considered as illustrative only of the principles of the invention. Further, since numerous modifications and changes will readily occur to those skilled in the art, it is not desired to limit the invention to the exact construction and operation shown and described, and accordingly all suitable modifications and equivalents may be resorted to, falling Within the scope of the invention as claimed.

What is claimed as new is as follows:

A chimney cover comprising a hood, depending legs on said hood adapted to seat on top of a chimney at opposite sides of a chimney flue to support the hood over a chimney flue in elevated position to cover and protect a chimney against rain entering the same While the chimney is open, and holddown means for said cover for maintaining the legs seated on a chimney comprising a weight adapted to be suspended in a chimney flue, and means suspending said Weight from said hood, said weight being tubular and of less width than a chimney flue to obviate interfering with updraft in a chimney flue, said suspending means comprising hanger bars converging downwardly relatively from said hood to said weight for downward wedging into a chimney flue to facilitate holding said hood seated.
